USG-Pro Starlink Dishy Wan 2 Failover

I have been running my UDM-Pro with my cable internet provider with little issue for some time but I have recently added a starlink dish to my system as a backup. The cable in my area is very flaky. The problem I am having is when my cable goes down for whatever reason it is not failing over to starlink. I am currently running firmware 1.9.2 on the UDM and both WAN devices show IP addresses. I have also tried plugging in starlink direct and thru its own router and either way it is not working. I have also tried plugging it into wan1 when wan1 goes down and it doesn’t seem to pick it up. Any suggestion would be great I am unsure where to go from here.

Thanks
